Painted live during Art Basel at the Basel House Mural Festival, Heading to the Unknown is an interactive perspective mural that invites both visual illusion and existential reflection. Using the wall and the sidewalk as a unified canvas, the piece depicts a red-and-white staircase that appears to rise into a gold-painted doorway — suggesting transition, elevation, or even escape.

The piece plays with forced perspective, giving passersby the ability to "walk into" the illusion, merging viewer and art in a brief moment of playful immersion. The door itself, shimmering with gold tones and streaks of black paint, stands like a portal — mysterious, open-ended, and symbolic.

On the adjacent wall reads the phrase "I’m heading to the unknown" — a caption as much about the artwork as it is about the artist’s creative journey and the vibe of Basel itself: chaotic, unpredictable, and full of potential.

The mural was signed with Gosa’s living day count, 11,919, marking not just a date, but a moment lived and documented in time — part of a larger personal system of time-stamping his creations.
